Description
Trials were conducted with dairy cows to investigate the feed efficiency of grass-clover mixture (wilted silage, silage made of fresh material with addition of foDTiic acid, artificially dried forage, pellets with varying portions of straw). The results obtained allow to draw the following conclusions:
As regards dry matter intake, digestibility, and feed efficiency, grass-dover for wilted silage should be wilted to give a OM content not exceeding 40 %.
Pelleting artificially dried grass-clover mixture and its use in mixed rations together with other separately pelleted components should be avoided.
The best feed efficiency is reached when dried grass-clover is converted into semifinished or finished feeds along with other ration components. ln such case, straw should account for at least 20 to 30% of the ration.
As part of semi-finished or finished feeds (pellets) up to 380 g of urea a day can be efficiently utilized by a dairy cow. However, the dosing plant should be made to work properly.
The processing of dried roughages, including straw, into semi-finished and finished feeds meets the requirements of industrial methods in production and feeding.
